[JIRA] [core] (JENKINS-20769) Failed to execute command Pipe.EOF

Sun, 16 Mar 2014 11:35:16 -0700

Sam Gleske commented on Bug JENKINS-20769

I have this issue though I may be able to provide a more reliable repeatable method. My setup is as follows.

-> Jenkins running in JBoss as jboss system user (RHEL 6.5) - jboss-eap-5.1.2 - Jenkins ver. 1.532.2
  -> slave.jar running on RHEL6.5 slave as jenkins system user which is started via SSH keys.
-> Eclipse Standard 4.3.2 - eclipse-standard-kepler-SR2-win32-x86_64
  -> Tried Mylyn build connector for Jenkins using both latest or weekly
  -> Execute a build from the Builds view.


When I run a build a couple of times every once in a while the JBoss server will crash completely.  Here's the log output.

In Eclipse, I get errors like the following.

I don't know what the plugin is doing over the API to cause this but since it works sometimes but not others I would agree it is likely a race condition.
